Abstract

A filter includes a porous molded article, which is a sintered material of mixed powder containing activated carbon powder and thermoplastic resin powder. When water having a specific electrical resistance value of 18 MΩ·cm or greater is caused to pass through the filter at a space velocity of 1200 hr, a specific electrical resistance value of the water after being caused to pass through the filter is 13 MΩ·cm or greater. To provide a filter capable of efficiently removing metal ions in a treatment liquid and capable of easily obtaining a solution having an extremely low metal ion content.
